Lore | While the species Pennisetum setaceum is considered invasive to California, selective plant breeding has resulted in attractive cultivated varieties that are seedless or do not produce viable seed, including Pennisetum setaceum 'Rubrum', 'Fireworks' and 'Skyrocket'. These three cultivars are non-invasive and safe for California gardening efforts. |
Average Size at Maturity | Moderate growing; reaches 2 to 4 ft. tall, 2 to 3 ft. wide. |

Design Ideas | This is without a doubt the most gorgeous Fountain Grass. Growing to four feet tall, its bronzed foliage is beautiful throughout the season, not just in autumn. It is indispensable for dry stream beds and a lovely fluffy accent in dry gardens. Provides wildlife habitat around water holes and ponds, and adds its billowy character to homegrown meadows. Makes a great erosion-control plant on slopes, both cut and fill. Equally at home in big Southwestern ceramic pots or classical Italian terra cotta on posts and walls, or ganged around entries, steps and gateways. Try three or four matched potted specimens spaced evenly on steps or line them against a bare, light colored stucco wall. |
